Web Hosting NewsAndover, Massachusetts, USA — VKernel, the number one provider of capacity planning and performance monitoring products for virtualized data centers and cloud environments, announced a vCPU sizing guide for VM administrators. In a new white paper entitled, “vCPU Sizing Considerations” by vExpert David Davis and VKernel Product Marketing Manager Alex Rosemblat, virtualization administrators will gain a deeper understanding of vCPU and be able to easily make the right decisions related to vCPU sizing.

Because vCPU is a finite resource in a server and is also one of the most dynamically demanded resources by the guest OS in each VM, vCPU VM allocation is very difficult. Furthermore, virtualization administrators need to avoid over-allocating vCPU’s because doing so wastes expensive server resources and will minimize ROI on that infrastructure. VM administrators face a difficultly in balancing the need to maximize ROI of the server hardware and the requirement for applications to perform optimally.

With the right tools and the guidance in this white paper, VM administrators will learn:

  • How to correctly size VMs in an environment
  • How to approach appropriate sizing of new VMs that need to be deployed
  • How to institute a regular CPU Sizing process for the data center
  • How CPU usage works at different levels of the virtualization “stack”
  • How to screen for CPU-based VM performance issues before attempting to optimize anenvironment
  • What VM performance metrics can provide insights on CPU and how to access them
